LT1634BCS8-5#PBF

Voltage Reference Overview

The LT1634BCS8-5#PBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output of 5V in an 8-lead plastic SOIC package. The device achieves 0.05% initial voltage accuracy and a maximum temperature coefficient of 25ppm/°C. Operating current is typically 15µA, with a maximum reverse operating current of 30mA. It functions within a commercial temperature range of 0°C to 70°C.

Voltage Reference Feature Summary

• Utilizes trimmed precision thin film resistors for high initial accuracy
• Operates at micropower levels suitable for battery applications
• Stable with capacitive loads without requiring external compensation

Voltage Reference Applications

• Portable meters
• Precision regulators
• A/D and D/A converters
• Calibrators

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when ordering. Confirm that the BC grade corresponds to the required 25ppm/°C drift specification rather than the lower drift A or I grades. Ensure the 8-pin SOIC footprint matches the target PCB layout constraints before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a stable 5V reference is needed with low power consumption. The BC grade offers a balance of cost and performance for commercial environments. Consider higher grades if tighter drift limits are necessary. Verify that the 30mA maximum current capability meets the load requirements of the application circuit.

Voltage Reference Part Context

This part belongs to the LT1634 family of micropower shunt references. It serves as a high-performance upgrade to older references like the LM185 or LT1004. The family includes various voltage options and packages, including MSOP and TO-92, catering to different space and thermal requirements.
